    Want to convert 32 bit data into 4 group of 8 bit data for UART

    hello I am making a UART transmitter which send data from FPGA sparten 3E to PC. here the problem is The size of the data is 32 bit. UART have limitation to send 8 bit data. I am converting 32 bit into 8 bits and give it to uart transmitter. It gives output but the order of the output is in...

    Want to convert 32 bit data into 4 group of 8 bit data for UART

    Re: [Moved] how to synchronize 32bit (live) data with UART on spartan 3E. Thanks all for replying I designed a digital filter,it gives 32 bit output. I want to tak that output in my laptop let's say in hyper terminal. So I make a code for UART which support 8 bit transmission at a time. I...

    Want to convert 32 bit data into 4 group of 8 bit data for UART

    [Moved] how to synchronize 32bit (live) data with UART on spartan 3E. Hello, I want to send 32 bit data (which is continuously coming from filter) through UART transmitter. I think I have to use block RAM with shift register. Can any on help me with this? I want some examples how to do this in...

    How to "ARCTAN" Function in VHDL

    Thanks all for replying I try to apply your given solutions but problem accrue in look up table as well as in CORDIC is there is less space remaning in FPGA board. So I have to cancle that idea. If am no wrong I can write a code using Taylor Series which is arctan(x)=x-x^3/3+x^5/5-x^7/7+ ... I...

    How to "ARCTAN" Function in VHDL

    I am a student and doing my final project. I need to find θ = atan (Y/X) in VHDL. I found a link https://standards.ieee.org/downloads/1076/1076.2-1996/math_real.vhdl in this they give different Math functions. Can any one tell me how can I write a code to find the phase value θ.

    VHDL UART code written by Bert Cuzea of alse-fr.com

    thank you for reply I am new with VHDL and FPGA. I just want to take data out from spartan 3E to PC the data is in digital form and it is continuous. I thought I can do using UART.

    VHDL UART code written by Bert Cuzea of alse-fr.com

    hello, I want to take the data from the FPGA Spartan 3E board to PC. I take code from https://www.edaboard.com/threads/183801/. They give code to transmit the data from PC to FPGA. and redy to use ISE file for Spartnan 3E. I have spartan 3E board, regarding UCF file I have a question. #FTDI...
